Mini Size High Power Fiber Amplifier Module

Description

YEDFA-CA-EM-B-27 series of fiber amplifiers are specially designed for FTTx, CATV, FDC and HFC analog amplification applications that require high reliability. Compared to conventional amplifiers, these modules are more compact, powerful, stable and reliable.

Both input and output signals are sampled and monitored with a feedback circuit. ACC (automatic current control) and APC (automatic power control) circuits are designed into the amplifier to ensure high stability and reliability of output power. Based on integrated power monitoring circuits, this amplifier features a RS-232 interface enabling connectivity to customer's control system.
